Perspective Diagrams and Infographics

These downloadable diagrams accompany The Art and Science of Perspective book series. They provide visual summaries of Perspective Category Theory, the functions and processes of perspective, projection systems, instrument perspective, perspective phenomena, and the wider taxonomy of visual and optical perspective.

Categories of Perspective

An overview of the principal categories and relationships within Perspective Category Theory.

Functions of Perspective

A systematic comparison of viewing, matching and representing functions across the imaging and projecting classes.

Perspective Imaging Process

An ontology of the optical imaging process, linking perspective targets, systems, methods, image forms, phenomena and appearance facets.

Instrument Perspective A

Looking, capturing and projecting/displaying: instruments and techniques used to observe, record and show visual reality.

Instrument Perspective B

Representing, measuring/modelling and simulating: instruments and systems used to construct, analyse and create visual appearances.

Perspective Projection Types

A classification of central, cylindrical, spherical, curvilinear and linear projection systems and their frameworks.

Parallel Projection Types

A visual classification of oblique, orthographic, axonometric and multi-view parallel projection systems.

Perspective Phenomena

A comprehensive map of extrinsic, intrinsic and environmental factors involved in perspective phenomena and visual perception.

Perspective Phenomena — Extrinsic Factors

A detailed analysis of spatial, formal, optical and atmospheric factors that transform the appearance of objects and scenes.

Taxonomy of Perspective

A wide-ranging visual taxonomy linking perspective classes, categories, processes, image forms, optical facets and perspective phenomena.
